The current code is very naive: * A R_OK check always succeeds if the file's attributes can be read at all * A W_OK check fails if the file has its DOS read-only attribute set * A W_OK check always succeeds for a directory (because read-only means something else for directories). Would you care to propose some wording for the docs? I'm quite happy to commit if we can come to an agreement. TJG
